<br>
Most of the notifications are documented here<br>
<a href="https://wiki.openstack.org/wiki/SystemUsageData" target="_blank">https://wiki.openstack.org/wiki/SystemUsageData</a><br>
<br>
But, you're correct that there is no versioning on these currently, but<br>
there are some efforts to fix this (specifically around CADF-support)<br>
<br>
Here's some more info on notifications if you're interested:<br>

Hope it helps!<br>
